? Hey guys. Changed all the appropriate plugs wires cap roter filters. The truck kind of flutters when it starts moving and through out driving. Will barly do 70 if going down hill. On long straight aways and especially on the slightest up hill grade it looses speed down to below 50 and I have to down shift to get back to 60. Also it seems to be running kind of rich. Any thoughts would be appreciated thanks. ?
